(4‐Nitrophenylsulfanylmethyl)triphenylstannane and (4‐nitrophenylsulfonylmethyl)triphenylstannane: R(X) rings (X is 10, 18 or 24) and C—H⋯π interactions

In the crystal structures of (4‐nitro­phenyl­sulfanyl­methyl)­tri­phenyl­stannane, Sn(C₆H₅)₃(C₇H₆NO₂S)], (I), and (4‐nitro­phenyl­sulfonyl­methyl)­tri­phenyl­stannane, Sn(C₆H₅)₃­(C₇H₆NO₄S)], (II), the mol­ecules are linked by paired C—H?O hydrogen bonds into centrosymmetric dimers which combine to form sheets. In (I), two such dimers form to give R(10) and R(24) rings. In (II), similar dimers form, here with R(10) and R(18) rings, but with an additional dimer due to the presence of the sulfone group, giving R(10) rings. In both structures, C—H?π interactions lead to a doubling of the width of the sheets.
